Could semen in bathwater remain viable following a period of 48 hours approx (-4 hours) result in an accidental pregnancy within female, provided that the she sat on the semen remnants and proceeded to masturbate. Water drained and bath refilled 44 hours later.Or would the aqueous environment be too harsh for sperm to live so long e.g Dilution of essential proteins, osmotic shock, ph and chlorinated tap water?
